Cloud VR Device for Motion-To-Photon (mtp) Latency Reduction

2. The cloud VR device of claim 1, wherein the movement start detection unit detects the movement of the client VR terminal through N (N is a natural number) degree of freedom (DoF) tracking sensors.

3. The cloud VR device of claim 2, wherein the movement start detection unit detects the movement of the client VR terminal through movement tracking of a user's head by positioning the N degree of freedom (DoF) tracking sensors outside the client VR terminal.

4. The cloud VR device of claim 1, wherein the Judder improvement unit obtains an angular velocity through N DoF tracking sensors during the movement start and predicts an orientation of a user's head according to an MTP latency time based on the angular velocity.

5. The cloud VR device of claim 4, wherein the Judder improvement unit dynamically adjusts the MTP latency time by determining a difference between the predicted orientation and an actual orientation of the user's head at a point in time according to the MTP latency time.

6. The cloud VR device of claim 1, wherein the video encoding processing unit provides an angular velocity and an angular acceleration according to the predicted orientation to the cloud VR server, and the cloud VR server determines encoding urgency of the video image to encode the video image.
